It has been suggested that global warming could be halted by fertilizing the oceans to increase the growth of algae. How might this affect the greenhouse effect?
A)Algal photosynthesis would use up more CO₂, which traps heat.
B)Algal photosynthesis would produce more O₂, which blocks light.
C)Algal photosynthesis would be inhibited by the addition of fertilizer.
D)Algae photosynthesis would use heat in place of photons.

Question

Quizplus · Accepted Answer

Algal photosynthesis involves the uptake of CO₂ and production of O₂. By increasing the growth of algae via ocean fertilization, more CO₂ would be consumed, leading to a reduction in atmospheric CO₂ concentrations. This would ultimately decrease the greenhouse effect, as CO₂ is a major contributor to this phenomenon.
